  The SAP error message SO2_TOOL045 indicates that there is an issue with the naming convention of event handlers in your SAP system. Specifically, the error states that event handler names must not begin with a digit. This is a validation rule in SAP to ensure that naming conventions are followed, which helps maintain consistency and avoid potential conflicts in the system.

  The primary cause of this error is that the name of the event handler you are trying to create or use starts with a numeric digit (0-9). SAP has specific naming conventions that must be adhered to, and one of these conventions is that names should not start with a digit.
  Solution:
  To resolve this error, you need to rename the event handler so that it does not begin with a digit. Here are the steps you can follow:

  Rename the Event Handler: Change the name of the event handler to start with a letter (A-Z or a-z) instead of a digit. For example, if your event handler is named 1EventHandler, you could rename it to EventHandler1 or A1EventHandler.
  
  
  Update References: If the event handler is referenced elsewhere in your code or configuration, make sure to update those references to match the new name.
  
  
  Test the Changes: After renaming the event handler and updating any references, test the functionality to ensure that everything works as expected and that the error no longer occurs.
